置。 A power synchronization signal generation circuit that generates a signal synchronized with zero volts of the commercial power supply, a control element that outputs a signal to the relay drive circuit when the signal of this circuit is input from the interrupt input terminal, and a control element that outputs a signal to the relay drive circuit. In the relay driven by the control element 1, after the signal from the power synchronization signal generation circuit 3 is input to the interrupt input terminal of the control element 1, the signal is output from the control element to the relay drive circuit 4. A relay control device characterized in that the sum of the time ta until the relay 51 is turned off and the delay time Tl for turning off the relay 51 is made to match the cycle T of the power supply cycle signal.
